Abstract
An apparatus for aerosol direct fluorination is disclosed in which a material to be fluorinated is formed into an aerosol prior to fluorination by introducing a vapor stream of the material to be fluorinated centrally into converging flows of carrier particles suspended in a gas and condensing the vapor onto the particles. Fluorine is contacted with the aerosol in an elongated fluorination reactor having microporous walls providing a substantially continuous influx of fluorine-containing gas which creates an increasing fluorine concentration gradient as the aerosol moves through the reactor and provides a barrier to prevent contact of the aerosol with the microporous walls. A photochemical stage includes an elliptical reflector with a light source of one focus and a flow of aerosol and fluorine at the others.
